input-generators.ts

The input-generators.ts file provides functions for generating inputs to the JWT Auth circuit. It includes utilities for JWT verification, input generation, and handling anonymous domains.

Key Interfaces:

export interface RSAPublicKey {
  n: string; // Base64-encoded modulus
  e: number; // Public exponent
}

export interface JWTInputGenerationArgs {
  maxMessageLength?: number;
  verifyAnonymousDomains?: boolean;
  anonymousDomainsTreeHeight?: number;
  anonymousDomainsTreeRoot?: bigint;
  emailDomainPath?: bigint[];
  emailDomainPathHelper?: number[];
}

Main Function:

async function generateJWTVerifierInputs(
  rawJWT: string,
  publicKey: RSAPublicKey,
  accountCode: bigint,
  params: JWTInputGenerationArgs = {},
);

Testing

To test the input generator, you can run the following command:

yarn test
